A method, non-transitory computer readable medium, and application server computing device that receives a request identifying an operation to be performed on an application and a plugin associated with the application. The operation corresponds to an application task in a workflow for a data storage network action. An operating system call is generated to execute the plugin, wherein the call comprises at least one argument that identifies the operation. A standard-out output is obtained from the plugin, wherein the output comprises at least an indication of a status of the operation. The output is parsed, a result object is generated based on the parsed output, and the result object is returned in response to the received request. The result object includes at least the indication of the status of the operation.
